Growth hormone and blood-glucose concentrations during cardiopulmonary bypass.
Plasma growth hormone (plasma GH) and blood-glucose concentrations were measured in 23 patients undergoing open heart surgery with moderate hypothermia. A significant increase in blood-glucose concentration occurred with sternotomy and increased during bypass, partly as a result of the exogenous glucose load from the perfusate. Following bypass, the blood-glucose remained above the pre-anaesthe...
متن کاملHypoxaemia during cardiopulmonary bypass.
For cardiopulmonary bypass during open-heart surgery we use a bubble oxygenator and a technique of haemodilution and moderate hypothermia. During the course of routine perfusion we have observed arterial desaturation in a number of patients and in five patients the desaturation was marked (SaO2<85%)'. The low arterial oxygen saturations occurred mainly in the rewarming period. This report is of...
متن کاملBlood Filtration During Cardiopulmonary Bypass
Particulate microembolization during extracorporeal circulation is thought to contribute to cerebral, pulmonary and other post-operative complications following cardiac surgical procedures. 11° Factors which have been implicated in microembolic phenomena during cardiopulmonary bypass include: 1 ) transfusion of stored blood ,I· 2 ' '· 11 ' ' 3 22 2) formation of platelet aggregates in the patie...
متن کاملProcoagulant triggers during cardiopulmonary bypass.
Recently, Boisclair et all has given us an important clue to show the main trigger to coagulation activity during cardiopulmonary bypass (CPB). They observed the increase of factor IX activation peptide during CPB, which shows a strong correlation with the increase of prothrombin fragment F1 + 2. In contrast, they found no significant increase in factor XIIa levels during CPB. This activation p...
متن کاملPupil changes during cardiopulmonary bypass.
Pupil diameter is used during anaesthesia to assess depth of anaesthesia and indicate cerebral hypoxia. This is especially so during cardiac bypass when other autonomic signs cannot be monitored. We have used a pupillometer to determine the effect of cardiopulmonary bypass on the pupil. We have also investigated if any effect was caused by washout of opioid from the central nervous system by al...
